Description

洗衣机washing machine 技术领域technical field
本发明涉及一种洗衣机。The present invention relates to a washing machine.
背景技术Background technique
例如，专利文献1中记载了一种能将液体洗涤剂自动投入洗涤兼脱水桶内的洗衣机。For example, Patent Document 1 describes a washing machine that can automatically inject liquid detergent into a washing and dehydrating tub.
专利文献1的洗衣机具备设置于外壳内并容纳液体洗涤剂的洗涤剂盒。洗涤剂盒通过由洗涤剂盒盖关闭补充洗涤剂的补充口来封闭内部，并且具有空气流入口和液体排出口。空气流入口与空气泵相连。当空气泵工作时，密闭的洗涤剂盒内的气压升高，洗涤剂盒内的洗涤剂被从液体排出口挤出，投入洗涤兼脱水桶内。用户不用在每次洗衣运转时都向洗衣机投入一次量的洗涤剂，很方便。The washing machine of Patent Document 1 is provided with a detergent box which is provided in a casing and accommodates a liquid detergent. The detergent box closes the interior by closing the replenishment port for replenishing the detergent by the detergent box cover, and has an air inflow port and a liquid discharge port. The air inlet is connected to the air pump. When the air pump works, the air pressure in the closed detergent box rises, and the detergent in the detergent box is squeezed out from the liquid discharge port and put into the washing and dewatering tub. The user does not need to input a quantity of detergent into the washing machine every time the washing operation is performed, which is very convenient.
此外，专利文献2中记载了一种具备超声波去污装置的洗衣机，该超声波去污装置包括蓄水的贮水桶和位于贮水桶的上方的超声波发生体。In addition, Patent Document 2 describes a washing machine provided with an ultrasonic decontamination device including a water storage tub that stores water and an ultrasonic generator positioned above the water storage tub.
专利文献2的洗衣机中，在超声波去污装置中，洗涤物的污垢附着部分设置在蓄有水的贮水桶内而开始去污运转。由超声波发生体产生的超声波能量作用于被水浸透的污垢附着部分而使污垢剥离。In the washing machine of Patent Document 2, in the ultrasonic decontamination device, the dirt adhering portion of the laundry is placed in a water storage tub in which water is stored, and the decontamination operation is started. The ultrasonic energy generated by the ultrasonic generator acts on the adhered portion of the water soaked in the dirt to peel off the dirt.
因此，可以认为实现了一种洗衣机，其具备能在洗衣运转时自动投入洗涤剂的功能和能通过超声波去污装置进行去污运转的功能。Therefore, it can be considered that a washing machine having a function of automatically injecting detergent during a washing operation and a function of performing a stain removal operation by an ultrasonic stain removal device is realized.
在如上所述的洗衣机中，进一步地，可以考虑在去污运转时将含有洗涤剂的水蓄留在贮水桶中从而实现去污效果的提高。In the washing machine as described above, further, it is conceivable that the water containing detergent is stored in the water storage tub during the decontamination operation to improve the decontamination effect.
但是，在采用这样结构的情况下，去污运转中所使用的水中所含的洗涤剂在运转结束后直接被废弃到机外，在这之后进行洗衣运转的情况下，无论是否进行了去污运转，都会自动投入规定量(例如与洗涤物的负荷量对应的量)的 洗涤剂。因此，很难通过将去污运转中所使用的洗涤剂用于后续的洗衣运转来减少洗衣运转中自动投入的洗涤剂的量。However, in the case of adopting such a structure, the detergent contained in the water used in the decontamination operation is directly discarded outside the machine after the end of the operation, and when the washing operation is performed after that, regardless of whether the decontamination is performed or not During operation, a predetermined amount of detergent (for example, an amount corresponding to the load of laundry) is automatically injected. Therefore, it is difficult to reduce the amount of the detergent automatically charged in the washing operation by using the detergent used in the stain removal operation for the subsequent washing operation.

全自动洗衣机1能进行各种运转模式的洗衣运转。洗衣运转中，按顺序执行清洗过程、中间脱水过程、漂洗过程以及最终脱水过程。The fully automatic washing machine 1 can perform washing operation in various operation modes. In the laundry operation, a washing process, an intermediate dehydration process, a rinsing process, and a final dehydration process are performed in sequence.
清洗过程和漂洗过程中，在洗涤脱水桶22内蓄有水的状态下，波轮24顺时针和逆时针旋转。通过波轮24的旋转，洗涤脱水桶22内产生水流。清洗过程中，通过产生的水流和水中所含的洗涤剂，洗涤物被清洗。漂洗过程中，通过产生的水流，洗涤物被漂洗。During the cleaning process and the rinsing process, the pulsator 24 rotates clockwise and counterclockwise when water is stored in the washing and dewatering tub 22 . Through the rotation of the pulsator 24, a water flow is generated in the washing and dewatering tub 22. During the washing process, the laundry is washed by the generated water flow and the detergent contained in the water. During the rinsing process, the laundry is rinsed by the generated water flow.
中间脱水过程和最终脱水过程中，洗涤脱水桶22和波轮24一体地高速旋转。通过洗涤脱水桶22中产生的离心力的作用，洗涤物被脱水。During the intermediate dehydration process and the final dehydration process, the washing and dehydrating tub 22 and the pulsator 24 are integrally rotated at a high speed. The laundry is dehydrated by the centrifugal force generated in the washing and dehydrating tub 22 .
在基于洗涤剂投入按钮716的操作设定了自动投入洗涤剂的情况下，在清洗过程中的供水时，洗涤剂通过供水装置80被自动投入洗涤脱水桶22内。这时，第三三通阀650被切换为使入水口651与第一出水口652连通的状态，第一水路612成为与贮留箱60隔断并与注水室611相连的状态。此外，第二三通阀640被切换为使第一入水口641与出水口643连通的状态，第一水路612成为在第二三通阀640的位置相连的状态。When the automatic injection of detergent is set based on the operation of the detergent injection button 716 , the detergent is automatically injected into the washing and dewatering tub 22 through the water supply device 80 during water supply during the washing process. At this time, the third three-way valve 650 is switched to the state in which the water inlet 651 and the first water outlet 652 communicate with each other, and the first water passage 612 is blocked from the storage tank 60 and connected to the water injection chamber 611 . In addition, the second three-way valve 640 is switched to a state in which the first water inlet 641 and the water outlet 643 communicate with each other, and the first water passage 612 is in a state of being connected at the position of the second three-way valve 640 .
首先，第一三通阀630被切换为使第二入水口632与出水口633连通的状态。由此，成为洗涤剂能流入第一水路612的状态。泵660工作，第一水路612内的泵660的上游侧的空气被抽吸，上游侧变为负压。由此，如图5的单点划线所示，洗涤剂盒400内的液体洗涤剂经由洗涤剂供给管430被抽吸至第一水路612内。与泵660的工作时间对应量的洗涤剂蓄于第一水路612内。First, the first three-way valve 630 is switched to a state in which the second water inlet 632 and the water outlet 633 communicate with each other. As a result, the detergent can flow into the first water passage 612 . The pump 660 operates, the air on the upstream side of the pump 660 in the first water passage 612 is sucked, and the upstream side becomes negative pressure. Thereby, as shown by the one-dot chain line in FIG. 5 , the liquid detergent in the detergent box 400 is sucked into the first water passage 612 via the detergent supply pipe 430 . The amount of detergent corresponding to the operating time of the pump 660 is stored in the first water passage 612 .
接着，第一三通阀630被切换为使第一入水口631与出水口633连通的状态。由此，成为洗涤剂不能流入第一水路612的状态。而且，第一水路612成为在第一三通阀630的位置相连的状态。如图6的实线箭头所示，供水阀620的第一阀621打开，来自水龙头的水被供给至第一水路612内。流过第一水路612内的水冲走蓄于第一水路612内的洗涤剂。被水冲走的洗涤剂与水一起流向注水室611，从注水口611a投入洗涤脱水桶22内。Next, the first three-way valve 630 is switched to a state in which the first water inlet 631 and the water outlet 633 communicate with each other. As a result, the detergent cannot flow into the first water passage 612 . Then, the first water passage 612 is connected to each other at the position of the first three-way valve 630 . As shown by the solid arrow in FIG. 6 , the first valve 621 of the water supply valve 620 is opened, and the water from the faucet is supplied into the first water passage 612 . The water flowing through the first water passage 612 washes away the detergent stored in the first water passage 612 . The detergent washed away by the water flows into the water filling chamber 611 together with the water, and is put into the washing and dewatering tub 22 from the water filling port 611a.
进而，供水阀620中，第一阀621打开的同时第二阀622打开，向洗涤脱水桶22内进行供水。如图6的虚线箭头所示，来自水龙头的水被供给至第二水路613内并流过第二水路613内到达注水室611，从注水口611a放出至洗涤脱水桶22内。这时，流过第二水路613的水的流量多于流过第一水路612的水的流量。当洗涤脱水桶22内的水位达到规定的清洗水位时，关闭第一阀621和第二阀622，结束供水。Furthermore, in the water supply valve 620 , the second valve 622 is opened at the same time as the first valve 621 is opened, and water is supplied into the washing and dehydrating tub 22 . 6, the water from the faucet is supplied into the second water passage 613, flows through the second water passage 613, reaches the water filling chamber 611, and is discharged into the washing and dewatering tub 22 from the water filling port 611a. At this time, the flow rate of the water flowing through the second water path 613 is larger than the flow rate of the water flowing through the first water path 612 . When the water level in the washing and dewatering tub 22 reaches a predetermined washing water level, the first valve 621 and the second valve 622 are closed to end the water supply.
在基于柔顺剂投入按钮717的操作而设定了自动投入柔顺剂的情况下，在漂洗过程中的供水时，柔顺剂通过供水装置80被自动投入洗涤脱水桶22内。这时，与清洗过程一样，第一水路612成为与注水室611相连的状态。此外，第一三通阀630被切换为使第一入水口631与出水口633连通的状态，第一水路612成为在第一三通阀630的位置相连的状态。When the automatic injection of the softener is set based on the operation of the softener injection button 717 , the softener is automatically injected into the washing and dehydrating tub 22 through the water supply device 80 during water supply during rinsing. At this time, as in the cleaning process, the first water passage 612 is in a state of being connected to the water injection chamber 611 . In addition, the first three-way valve 630 is switched to a state in which the first water inlet 631 and the water outlet 633 communicate with each other, and the first water passage 612 is in a state of being connected at the position of the first three-way valve 630 .
首先，第二三通阀640被切换为使第二入水口642与出水口643连通的状态。由此，成为柔顺剂能流入第一水路612的状态。泵660工作，如图6的双点划线所示，柔顺剂盒500内的液体柔顺剂经由柔顺剂供给管530被抽吸至第一水路612内。与泵660的工作时间对应量的柔顺剂蓄于第一水路612内。First, the second three-way valve 640 is switched to a state in which the second water inlet 642 and the water outlet 643 communicate with each other. As a result, the softener can flow into the first water passage 612 . The pump 660 works, and as shown by the double-dot chain line in FIG. 6 , the liquid softener in the softener box 500 is sucked into the first water passage 612 through the softener supply pipe 530 . An amount of softener corresponding to the operating time of the pump 660 is stored in the first water passage 612 .
接着，第二三通阀640被切换为使第一入水口641与出水口643连通的状态。由此，成为柔顺剂能流入第一水路612的状态。而且，第一水路612成为在第二三通阀640的位置相连的状态。如图6的实线箭头所示，第一阀621打 开，来自水龙头的水被供给至第一水路612内。蓄于第一水路612内的柔顺剂被流过第一水路612内的水冲走而流向注水室611，从注水口611a投入洗涤脱水桶22内。Next, the second three-way valve 640 is switched to a state in which the first water inlet 641 and the water outlet 643 communicate with each other. As a result, the softener can flow into the first water passage 612 . Then, the first water passage 612 is in a state of being connected at the position of the second three-way valve 640 . As shown by the solid arrow in Fig. 6 , the first valve 621 is opened, and water from the faucet is supplied into the first water passage 612. The softener stored in the first water passage 612 is washed away by the water flowing through the first water passage 612 and flows into the water filling chamber 611, and is put into the washing and dewatering tub 22 from the water filling port 611a.
进而，与清洗过程一样，同时打开第二阀622和第一阀621，向洗涤脱水桶22内进行供水。Furthermore, as in the cleaning process, the second valve 622 and the first valve 621 are simultaneously opened to supply water into the washing and dehydrating tub 22 .
清洗过程和漂洗过程中的洗涤脱水桶22内的水位即水量根据供水前检测出的洗涤物的负荷量来决定。并且，投入洗涤脱水桶22内的液剂的量即液剂的使用量根据水量来决定。The water level, that is, the amount of water in the washing and dewatering tub 22 during the washing process and the rinsing process, is determined according to the load amount of the laundry detected before water supply. In addition, the amount of the liquid agent put into the washing and dewatering tub 22, that is, the usage amount of the liquid agent is determined according to the amount of water.
例如，相对于基准水量(例如30升)的液剂的量与各种液剂的种类建立对应，预先存储于存储部802。用户通过规定的设定操作，从各种液剂的种类中选择并设定洗涤剂盒400和柔顺剂盒500中收容的液剂的种类。控制部801从存储部802读出设定种类的相对于基准水量的液剂的量，由读出的液剂的量和根据负荷量确定的水量，计算出与该水量相符的液剂的量，将计算出的液剂的量作为这次洗衣运转中的液剂的使用量。在通过洗涤剂投入按钮716和柔顺剂投入按钮717设定为了“大量”或者“少量”的情况下，将计算出的液剂的量增加或减少规定的比例来作为液剂的使用量。需要说明的是，关于在清洗过程的供水之前进行的用于确定在洗衣运转中的洗涤剂的使用量的处理，后面详细地进行说明。For example, the amount of liquid medicine with respect to the reference water amount (for example, 30 liters) is associated with each type of liquid medicine, and is stored in the storage unit 802 in advance. The user selects and sets the types of liquid chemicals stored in the detergent box 400 and the softener box 500 from various types of liquid chemicals through a predetermined setting operation. The control unit 801 reads the amount of the liquid medicine of the set type relative to the reference water amount from the storage unit 802, and calculates the amount of the liquid medicine corresponding to the water amount from the read amount of the liquid medicine and the water amount determined by the load amount. , and use the calculated amount of the liquid agent as the liquid agent usage in this washing operation. When the detergent injection button 716 and the softener injection button 717 are set to "large amount" or "small amount", the calculated liquid agent amount is increased or decreased by a predetermined ratio as the liquid agent usage amount. In addition, the process for determining the usage-amount of the detergent in a washing|cleaning operation performed before the water supply of a washing|cleaning process is demonstrated in detail later.
在清洗过程的供水时，确定的使用量的洗涤剂通过泵660的工作而从洗涤剂盒400导入供水单元600的第一水路612。同样地，在漂洗过程的供水时，确定的使用量的柔顺剂通过泵660的工作而从柔顺剂盒500导入供水单元600的第一水路612。During the water supply in the cleaning process, the determined usage amount of the detergent is introduced from the detergent box 400 to the first water passage 612 of the water supply unit 600 by the operation of the pump 660 . Similarly, during the water supply in the rinsing process, the softener in the determined usage amount is introduced from the softener box 500 to the first water channel 612 of the water supply unit 600 through the operation of the pump 660 .
需要说明的是，在未设定自动投入洗涤剂的情况下，清洗过程中的供水时不从洗涤剂盒400内向供水单元600导入洗涤剂和向第一水路612供给自来水，并且不向洗涤脱水桶22内自动投入洗涤剂。这种情况下，只通过供水单元600的第二水路613向洗涤脱水桶22的供水。洗涤剂被用户手动投入洗涤脱水桶22内。同样地，在未设定自动投入柔顺剂的情况下，最终漂洗过程中的供水时不从柔顺剂盒500内向供水单元600导入柔顺剂和向第一水路612供给自来水，并且不向洗涤脱水桶22内自动投入柔顺剂。这种情况下，只通过供水单元600 的第二水路613向洗涤脱水桶22的供水。柔顺剂被用户手动投入洗涤脱水桶22内。It should be noted that, when the automatic detergent injection is not set, detergent is not introduced into the water supply unit 600 from the detergent box 400 and tap water is not supplied to the first water path 612 during the water supply during the washing process, and the washing and dehydration are not supplied. Detergent is automatically put into the tub 22 . In this case, water is supplied to the washing and dehydrating tub 22 only through the second water passage 613 of the water supply unit 600 . The detergent is manually put into the washing and dehydrating tub 22 by the user. Similarly, if the automatic injection of softener is not set, the softener is not introduced into the water supply unit 600 from the softener box 500 and tap water is not supplied to the first water path 612 during the water supply in the final rinsing process, and the washing and dehydrating tub is not supplied. The softener is automatically injected within 22. In this case, water is supplied to the washing and dehydrating tub 22 only through the second water passage 613 of the water supply unit 600 . The softener is manually put into the washing and dehydrating tub 22 by the user.
全自动洗衣机1能通过超声波去污装置50来进行去污运转。The fully automatic washing machine 1 can perform decontamination operation by the ultrasonic decontamination device 50 .
在去污运转时，从贮留箱60向贮水桶210供给去污水之后，洗涤物的污垢附着部分被置于贮水桶210与超声波发生体110之间。污垢附着部分被蓄于贮水桶210内的去污水浸泡，并且与超声波发生体110的前端面接触。当超声波发生体110工作时，从其前端产生超声波。通过超声波的作用，从被去污物中剥离污垢。这时，通过加上洗涤剂的力，去污力提高。During the decontamination operation, after the decontaminated water is supplied from the storage tank 60 to the water storage tub 210 , the dirt adhering portion of the laundry is placed between the water storage tub 210 and the ultrasonic generator 110 . The dirt adhering portion is soaked in the decontaminated water stored in the water storage tub 210 , and is in contact with the front end surface of the ultrasonic generator 110 . When the ultrasonic generator 110 operates, ultrasonic waves are generated from the front end thereof. The dirt is stripped from the dirt being removed by the action of ultrasonic waves. At this time, by adding the force of the detergent, the detergency is improved.
在去污运转中的供水时，在向贮水桶210进行供水之前，通过供水装置80向贮留箱60内供给去污水。这时，供给阀61关闭。需要说明的是，在基于洗涤剂投入按钮716的操作而设定成去污运转中不使用洗涤剂的情况下，不投入洗涤剂盒400内的洗涤剂，不含洗涤剂的水被供给至贮留箱60内。In the water supply during the decontamination operation, before the water supply to the water storage tank 210 , the decontaminated water is supplied into the storage tank 60 through the water supply device 80 . At this time, the supply valve 61 is closed. It should be noted that, when the detergent is not used in the decontamination operation based on the operation of the detergent injection button 716, the detergent in the detergent box 400 is not injected, and water without detergent is supplied to the Inside the storage tank 60 .
首先，第三三通阀650被切换为使入水口651与第二出水口653连通的状态。由此，第一水路612成为与注水室611隔断并经由分支水路616与贮留箱60相连的状态。与清洗过程一样，在第一三通阀630被切换为能使洗涤剂流入第一水路612的状态之后，泵660工作，洗涤剂盒400内的液体洗涤剂被抽吸至第一水路612内，蓄于第一水路612内。First, the third three-way valve 650 is switched to a state in which the water inlet 651 and the second water outlet 653 communicate with each other. As a result, the first water passage 612 is in a state of being blocked from the water injection chamber 611 and connected to the storage tank 60 via the branch water passage 616 . Similar to the cleaning process, after the first three-way valve 630 is switched to a state in which the detergent can flow into the first water channel 612 , the pump 660 is activated, and the liquid detergent in the detergent box 400 is sucked into the first water channel 612 . , stored in the first waterway 612 .
接着，第一三通阀630被切换为使洗涤剂导入路径关闭并使第一水路612在第一三通阀630的位置相连的状态。然后，供水阀620的第一阀621打开，来自水龙头的水被供给至第一水路612内。蓄于第一水路612内的洗涤剂被流过第一水路612内的水冲走，洗涤剂与水混合成为去污水。去污水经过分支水路616流入贮留箱60内。当贮留箱60内蓄有规定量的去污水时，第一阀621关闭。Next, the first three-way valve 630 is switched to a state in which the detergent introduction path is closed and the first water passage 612 is connected at the position of the first three-way valve 630 . Then, the first valve 621 of the water supply valve 620 is opened, and the water from the faucet is supplied into the first water passage 612 . The detergent stored in the first water passage 612 is washed away by the water flowing through the first water passage 612, and the detergent is mixed with the water to become decontaminated water. The decontaminated water flows into the storage tank 60 through the branch water channel 616 . When a predetermined amount of decontaminated water is stored in the storage tank 60, the first valve 621 is closed.
打开供给阀61，贮留箱60内的去污水经由供给喷嘴62被供给至贮水桶210内。然后，去污运转中，每当贮水桶210内的去污水由于被洗涤物吸水而减少时，相应量的去污水会从贮留箱60补给向贮水桶210。The supply valve 61 is opened, and the decontaminated water in the storage tank 60 is supplied into the water storage tub 210 through the supply nozzle 62 . Then, during the decontamination operation, whenever the decontaminated water in the water storage tub 210 decreases due to water absorption by the laundry, a corresponding amount of decontaminated water is replenished from the storage tank 60 to the water storage tub 210 .
当贮留箱60内的去污水供给至贮水桶210时，贮留箱60内的去污水的剩余量会变少。这种情况下，再次从供水装置80向贮留箱60内进行去污水的供 给。需要说明的是，在去污运转开始时上一次去污运转中所使用的去污水残留于贮水桶210而基本上不会从贮留箱60向贮水桶210供给去污水的情况下，不向贮留箱60进行第二次的去污水供给。When the decontaminated water in the storage tank 60 is supplied to the water storage tank 210, the remaining amount of the decontaminated water in the storage tank 60 will decrease. In this case, the decontaminated water is supplied from the water supply device 80 into the storage tank 60 again. It should be noted that when the decontamination operation used in the previous decontamination operation remains in the water storage tank 210 at the start of the decontamination operation, and the decontaminated water is not basically supplied from the storage tank 60 to the water storage tank 210, The storage tank 60 performs the second decontamination supply.
在向贮留箱60内进行去污水的供给之前，进行用于确定投入贮留箱60内的洗涤剂的量即洗涤剂的使用量的处理。以下，将该处理称为去污洗涤剂量确定处理。Before supplying the decontaminated water into the storage tank 60, a process for determining the amount of the detergent put into the storage tank 60, that is, the usage amount of the detergent, is performed. Hereinafter, this process will be referred to as a decontamination detergent amount determination process.
图10是表示去污洗涤剂量确定处理的流程图。FIG. 10 is a flowchart showing a process of determining the amount of the decontamination detergent.
如上所述，用户能通过操作洗涤剂投入按钮716来选择、设定是否使用洗涤剂、将洗涤剂的使用量设为正常、大量、少量中的任一者。As described above, the user can select and set whether to use the detergent, or set the usage amount of the detergent to any of normal, large, and small amounts by operating the detergent input button 716 .
参照图10，控制部801判定是否设定成了使用洗涤剂(S101)。在不设定为使用洗涤剂的情况下(S101：否)，控制部801将本次洗涤剂的使用量设定为零(S102)。Referring to Fig. 10 , the control unit 801 determines whether or not the detergent is set to be used (S101). When the detergent is not set to be used ( S101 : NO), the control unit 801 sets the current usage amount of the detergent to zero ( S102 ).
在设定为使用洗涤剂的情况下(S101：是)，控制部801计算出洗涤剂的基本使用量(S103)。基本使用量根据贮存在洗涤剂盒400内的洗涤剂的种类而变更。控制部801例如从存储部802读出洗涤剂盒400内的洗涤剂的种类中的相对于基准水量的洗涤剂的量，将读出的量减少规定的比例来作为基本使用量。接着，控制部801判定是否设定成了大量使用洗涤剂、是否设定成了少量使用洗涤剂(S104、S105)。When the detergent is set to be used ( S101 : YES), the control unit 801 calculates the basic usage amount of the detergent ( S103 ). The basic usage amount is changed according to the type of detergent stored in the detergent box 400 . The control unit 801 reads, for example, the amount of detergent relative to the reference water amount among the types of detergent in the detergent box 400 from the storage unit 802, and reduces the read amount by a predetermined ratio as the basic usage amount. Next, the control unit 801 determines whether the detergent is set to be used in a large amount and the detergent is set to be used in a small amount ( S104 , S105 ).
在设定为大量的情况下(S104：是)，控制部801将本次洗涤剂的使用量确定为基本使用量的两倍的量(S106)。在设定为少量的情况下(S105：是)，控制部801将本次洗涤剂的使用量确定为基本使用量的二分之一的量(S107)。在既不设定为大量也不设定为少量而是设定为正常的情况下(S105：否)，控制部801将本次洗涤剂的使用量确定为基本使用量(S108)。When a large amount is set (S104: YES), the control part 801 determines the usage-amount of this detergent as an amount twice the basic usage-amount (S106). When it is set to a small amount (S105: YES), the control part 801 determines the usage-amount of this detergent as the amount of half of the basic usage-amount (S107). When it is set to be normal, neither a large amount nor a small amount is set (S105: NO), the control part 801 determines the usage-amount of this detergent as a basic usage-amount (S108).
需要说明的是，在设定为大量的情况下增加基本使用量的比例也可以不是两倍而是其他比例。同样地，在设定为少量的情况下减少基本使用量的比例也可以不是二分之一而是其他比例。此外，去污运转中，在向贮留箱60内供给两次去污水的情况下，在第一次的去污洗涤剂量确定处理和第二次的去污洗涤剂量确定处理中，可以使S101中计算出的基本使用量相同。或者，考虑到供给的 去污水的量会减少与贮留箱60内残留的去污水相应的量，也可以是，第二次的去污洗涤剂量确定处理中的基本使用量比第一次的去污洗涤剂量确定处理中的基本使用量少。It should be noted that, in the case of setting a large amount, the ratio of increasing the basic usage amount may not be twice but other ratios. Similarly, in the case of setting a small amount, the ratio of reducing the basic usage amount may not be 1/2 but other ratios. In addition, in the decontamination operation, when decontaminated water is supplied into the storage tank 60 twice, in the first decontamination detergent amount determination process and the second decontamination detergent amount determination process, S101 may be used. The base usage calculated in is the same. Alternatively, considering that the amount of decontaminated water to be supplied is reduced by an amount corresponding to the amount of decontaminated water remaining in the storage tank 60, the basic usage amount in the second decontamination detergent amount determination process may be smaller than that in the first time. The amount of detersive detergent determines the basic amount used in the treatment.
这样，在向贮留箱60内供给去污水时，确定好的使用量的洗涤剂通过泵660的工作而从洗涤剂盒400导入到供水单元600的第一水路612。供给去污水一次时，去污运转中的洗涤剂的使用量为一次的使用量，供给去污水两次时，去污运转中的洗涤剂的使用量为两次的使用量。在确定好的使用量为零的情况即不使用洗涤剂的情况下，洗涤剂盒400内的洗涤剂不被导入第一水路612，不含洗涤剂的水通过第一水路612被供给到贮留箱60内。In this way, when the decontaminated water is supplied into the storage tank 60 , the determined usage amount of the detergent is introduced from the detergent box 400 to the first water passage 612 of the water supply unit 600 by the operation of the pump 660 . When the decontamination is supplied once, the usage amount of the detergent in the decontamination operation is the amount used once, and when the decontamination is supplied twice, the usage amount of the detergent in the decontamination operation is the amount used twice. When the determined usage amount is zero, that is, when no detergent is used, the detergent in the detergent box 400 is not introduced into the first water passage 612 , and water without detergent is supplied to the storage tank through the first water passage 612 . Keep in box 60.
去污运转中的洗涤剂的使用量被存储到存储部802。每当进行去污运转时，存储部802内的洗涤剂的使用量被更新为该去污运转中的洗涤剂的使用量。The usage amount of the detergent during the decontamination operation is stored in the storage unit 802 . Every time the decontamination operation is performed, the usage amount of the detergent in the storage unit 802 is updated to the usage amount of the detergent in the decontamination operation.
去污运转结束时，在将去污运转中所使用的洗涤剂再利用于洗衣运转的情况下，用户将设置于贮水部200的杆部244b向前方移动而打开排水阀242，将去污水通过排水口241从贮水桶210内向洗涤脱水桶22内排出(参照图5的(b))。这时，供给阀61已被打开，残留于贮留箱60内的去污水也经过贮水桶210向洗涤脱水桶22内排出。当贮水桶210内和贮留箱60内双方的去污水被排到洗涤脱水桶22内时，用户将杆部244b归位而关闭排水阀242。At the end of the decontamination operation, when the detergent used in the decontamination operation is to be reused in the laundry operation, the user moves the rod portion 244b provided in the water storage unit 200 forward to open the drain valve 242, and drain the decontamination. The water is discharged from the water storage tub 210 into the washing and dewatering tub 22 through the drain port 241 (refer to FIG. 5( b )). At this time, the supply valve 61 is already opened, and the decontaminated water remaining in the storage tank 60 is also discharged into the washing and dewatering tub 22 through the water storage tub 210 . When the decontaminated water in both the water storage tub 210 and the storage tank 60 is drained into the washing and dewatering tub 22, the user returns the rod portion 244b to close the drain valve 242.
通过去污运转而去污的洗涤物中含有去污水。因此，贮水桶210内和贮留箱60内的去污水被供给至洗涤脱水桶22内，并且含有去污水的洗涤物被投入洗涤脱水桶22内，其结果是，与去污运转中所使用的量几乎相等的量的洗涤剂被投入洗涤脱水桶22内。Decontamination is contained in the laundry decontaminated by the decontamination operation. Therefore, the decontaminated water in the water storage tub 210 and the storage tank 60 is supplied into the washing and dewatering tub 22, and the laundry containing decontaminated water is put into the washing and dewatering tub 22. As a result, it is the same as that used in the decontamination operation. An almost equal amount of detergent is put into the washing and dewatering tub 22 .
接着，对用于确定洗衣运转中的洗涤剂的使用量的处理进行说明。以下，将该处理称为洗衣洗涤剂量确定处理。洗衣洗涤剂量确定处理在进行清洗过程的供水之前执行。Next, the process for determining the usage-amount of the detergent in the washing operation will be described. Hereinafter, this process is referred to as laundry detergent amount determination process. The laundry detergent amount determination process is performed before the water supply for the washing process.
图11是表示确定洗涤剂量洗涤处理的流程图。Fig. 11 is a flowchart showing a washing process of determining the amount of detergent.
参照图11，控制部801计算洗涤剂的第一基本使用量(S201)。例如，如上所述，相对于基准水量的洗涤剂的量与各种洗涤剂的种类相对应地预先存储于存储部802。控制部801从存储部802读出相对于用户设定的种类的基准水量 的洗涤剂的量，根据读出的洗涤剂的量和基于洗涤物的负荷量而确定的水量，计算出与该水量相符的洗涤剂的量，将计算出的洗涤剂的量设为第一基本使用量。11, the control part 801 calculates the 1st basic usage-amount of a detergent (S201). For example, as described above, the amount of detergent with respect to the reference water amount is stored in the storage unit 802 in advance in association with each type of detergent. The control unit 801 reads from the storage unit 802 the amount of detergent relative to the reference water amount of the type set by the user, and calculates the amount of water corresponding to the read amount of the detergent and the water amount determined based on the load of the laundry. In accordance with the amount of detergent, the calculated amount of detergent is set as the first basic usage amount.
接着，控制部801判定是否设定成了大量使用洗涤剂、是否设定成了少量使用洗涤剂(S202、S203)。如上所述，用户能通过操作洗涤剂投入按钮716来选择、设定洗涤剂的使用量为正常、大量、少量中的任一者。Next, the control unit 801 determines whether the detergent is set to be used in a large amount and the detergent is set to be used in a small amount ( S202 , S203 ). As described above, the user can select and set the usage amount of the detergent to be any of normal, large, and small by operating the detergent injection button 716 .
在设定为大量的情况下(S202：是)，控制部801将第一基本使用量的1.2倍的量设为第二基本使用量(S204)。在设定为少量的情况下(S203：是)，控制部801将第一基本使用量的0.8倍的量设为第二基本使用量(S205)。在既既不设定为大量也不设定为少量而是设定为正常的情况下(S203：否)，控制部801将第一基本使用量设为第二基本使用量(S206)。需要说明的是，在设定为大量的情况下增加第二基本使用量的比例也可以不是1.2倍而是其他比例。同样地，在设定为少量的情况下减少第二基本使用量的比例也可以不是0.8倍而是其他比例。When a large amount is set ( S202 : YES), the control unit 801 sets an amount 1.2 times the first basic usage amount as the second basic usage amount ( S204 ). When a small amount is set ( S203 : YES), the control unit 801 sets an amount 0.8 times the first basic usage amount as the second basic usage amount ( S205 ). If it is set to be neither a large amount nor a small amount but is set to be normal ( S203 : NO), the control unit 801 sets the first basic usage amount as the second basic usage amount ( S206 ). It should be noted that, in the case of setting a large amount, the ratio of increasing the second basic usage amount may not be 1.2 times but other ratios. Similarly, in the case of setting a small amount, the ratio of reducing the second basic usage amount may not be 0.8 times but other ratios.
接着，控制部801判定是否设定成了节约洗涤剂(S207)。在进行去污运转之后，在将该去污运转中所使用的洗涤剂再利用于了洗衣运转的情况下即将残留于贮水桶210和贮留箱60的去污水移到了洗涤脱水桶22的情况下，用户操作洗涤剂节约按钮718。由此，从操作检测部803向控制部801输出再利用信号。控制部801基于被输出了再利用信号而设定为节约洗涤剂。Next, the control unit 801 determines whether or not the detergent saving is set (S207). When the detergent used in the decontamination operation is reused in the laundry operation after the decontamination operation, that is, the decontaminated water remaining in the water storage tub 210 and the storage tank 60 is moved to the washing and dewatering tub 22 Next, the user operates the detergent saving button 718 . Thereby, the reuse signal is output from the operation detection unit 803 to the control unit 801 . The control unit 801 is set to economize on the detergent based on the output of the reuse signal.
在设定为节约洗涤剂的情况下(S207：是)，控制部801读出存储部802中存储的去污运转中的洗涤剂的使用量，将从第二基本使用量中减去去污运转中的洗涤剂的使用量的量确定为本次洗衣运转中的洗涤剂的使用量(S208)。另一方面，在不设定为节约洗涤剂的情况下(S207：否)，控制部801将第二基本使用量确定为本次洗衣运转中的洗涤剂的使用量(S209)。需要说明的是，设定为节约洗涤剂时的洗涤剂的使用量成为从不设定为节约洗涤剂时的洗涤剂的使用量中减去去污运转中的洗涤剂的使用量的量。When the detergent saving is set (S207: YES), the control unit 801 reads out the usage amount of the detergent during the decontamination operation stored in the storage unit 802, and subtracts the decontamination from the second basic usage amount. The amount of the used amount of the detergent in the operation is determined as the used amount of the detergent in the current washing operation (S208). On the other hand, when the detergent saving is not set ( S207 : NO), the control unit 801 determines the second basic usage amount as the usage amount of the detergent in the current washing operation ( S209 ). In addition, the usage-amount of the detergent at the time of setting to economize the detergent is the quantity which subtracted the usage-amount of the detergent in the decontamination operation from the usage-amount of the detergent at the time of not setting it to economize the detergent.
通过从贮水桶210供给去污水，在清洗过程中的供水前，与去污运转中的洗涤剂的使用量几乎相等的洗涤剂被投入到洗涤脱水桶22中。因此，在清洗过程的供水时，如果洗涤脱水桶22中投入了S208中确定的使用量的洗涤剂的话， 则洗涤脱水桶22内的洗涤剂的量成为与S209中确定的洗涤剂的使用量几乎相等的量。By supplying the waste water from the water storage tank 210 , the detergent in an amount almost equal to the usage amount of the detergent in the decontamination operation is put into the washing and dewatering tank 22 before the water supply in the cleaning process. Therefore, during the water supply of the washing process, if the detergent with the usage amount determined in S208 is put into the washing and dewatering tub 22, the amount of the detergent in the washing and dewatering tub 22 becomes the same as the usage amount of the detergent determined in S209. almost equal amounts.

例如，上述实施方式中，采用贮水桶210和贮留箱60双方的去污水通过排出部240向洗涤脱水桶22排出的结构。但是，也可以采用贮水桶210内的去污水向洗涤脱水桶22排出而贮留箱60内的去污水不向洗涤脱水桶22内排出的结构。这种情况下，在图11所示的洗衣洗涤剂量确定处理的S208中，将从第二基本使用量中减去相当于贮水桶210的容量的去污水中所含的洗涤剂的量的量确定为本次洗衣运转中的洗涤剂的使用量即可。For example, in the above-described embodiment, a structure is adopted in which the decontaminated water from both the water storage tub 210 and the storage tank 60 is discharged to the washing and dewatering tub 22 through the discharge portion 240 . However, it is also possible to adopt a configuration in which the decontaminated water in the water storage tank 210 is discharged to the washing and dewatering tub 22 and the decontaminated water in the storage tank 60 is not discharged into the washing and dewatering tub 22 . In this case, in S208 of the laundry detergent amount determination process shown in FIG. 11 , the amount of the detergent contained in the waste water corresponding to the capacity of the water storage tub 210 is subtracted from the second basic usage amount What is necessary is just to determine the usage-amount of the detergent in this washing|cleaning operation.
此外，上述实施方式中，排出部240采用包括形成于贮水桶210的排水口 241、关闭排水口241的排水阀242以及关闭排水阀242的开闭机构部243的结构。但是，只要是能将去污水从贮水桶210内向洗涤脱水桶22内排出的结构，可以使用任意结构的排出部。例如，也可以使用如下结构的排出部：在排水承接部70连接有面向洗涤脱水桶22的上方的供给软管，通过切换阀来对要将排水承接部70所承接的去污水导向排水软管41还是导向供给软管进行切换。In addition, in the above-described embodiment, the discharge portion 240 has a configuration including the drain port 241 formed in the water storage tank 210, the drain valve 242 for closing the drain port 241, and the opening and closing mechanism portion 243 for closing the drain valve 242. However, as long as it is a structure capable of discharging the decontaminated water from the water storage tub 210 into the washing and dewatering tub 22, any configuration of the discharge portion can be used. For example, a discharge unit having a configuration in which a supply hose facing the upper side of the washing and dewatering tub 22 is connected to the drain receiving part 70 and a switching valve may be used to guide the waste water to be received by the drain receiving part 70 to the drain hose 41 also guides the supply hose for switching.
